Service Worker Caching, PlaybackRate and Blob URLs for Audio and Video on Chrome for Android

From version 52, Android Chrome uses the same media stack as desktop Chrome, rather than relying on the underlying platform implementation. This enables service worker media caching, variable playback rates, blob URLs on Android, MediaStream passing between APIs, and easier cross-platform debugging.

The Media Source API enables JavaScript to construct media streams for playback. From Chrome 50, it's possible to use SourceBuffer sequence mode to ensure media segments are automatically relocated in the timeline in the order they were appended, without gaps between them.

MediaStream Deprecations

The MediaStream API represents synchronized streams of audio or video. MediaStream.ended, MediaStream.label and MediaStream.stop() are being deprecated. Use MediaStream.active, MediaStreamTrack.label and MediaStreamTrack.stop() instead.

Media playback notifications for Chrome on Android

When audio or video is playing on a web page, a notification showing the page title and a play/pause button is displayed in the notification tray and on the lock screen. The notification can be used to pause/resume play or return to the page playing the media.
